            Bug ID: 103244
           Summary: CY4672: Left click sends additional BTN_FORWARD
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: oleid at mescharet.de

Dear all,

the mouse "iONE Lynx-R17Nano" of my new wireless keyboard+mouse combo
incorrectly sends BTN_FORWARD after sending BTN_LEFT when performing a left
click. Here the corresponding output from libinput-debug-events:

-event6   POINTER_BUTTON    +4.73s      BTN_LEFT (272) pressed, seat count: 1
 event6   POINTER_BUTTON    +4.73s      BTN_FORWARD (277) pressed, seat count:
1
 event6   POINTER_BUTTON    +4.81s      BTN_LEFT (272) released, seat count: 0
 event6   POINTER_BUTTON    +4.81s      BTN_FORWARD (277) released, seat count:
0

This confuses gnome-shell and this mouse is useless for left-clicks. Disabling
BTN_FORWARD via xorg.conf, everthing is fine. But sadly, I couldn't find a way
to do that for wayland. So I'm looking for a way not to generate the event at
all.

These are the devices in question:


Device:           Cypress Semiconductor CY4672 PRoC LP RDK Bridge

For the records, I'm using ArchLinux, which currently has libinput-1.8.3.

Any idea where to start digging?

Kind regards!
